6.2 Clock Generator
The clock generator provides the clock signals to the CPU and peripheral hardware and its configuration is
shown in Figure 6-1.
The operation of the clock generation circuit is determined by the processor clock control register (PCC) and
system clock control register (SCC).
Two types of system clocks are available: main system clock and subsystem clock.
Furthermore, the instruction execution time can be changed.
